I designed a PC board in Eagle for the Silicon Labs CP2101 USB-to-UART Serial Converter chip. These are awesome little ICs. Very simple to use. Had the boards made at DorkbotPDX, and as usual they came out pretty good.

(NOTE: This chip has been discontinued. I built a board for their newer CP210...

I designed a simple PC board for the Microchip MCP2200 in Eagle and had some boards made at DorkbotPDX. They turned out really nice. This chip is a preprogrammed version of Microchip's PIC18F14K50. As well as being a good serial converter, it also has eight GPIO pins.

A guy emailed me wanting to know how to write C code to do a servo slowdown device like this PICAXE one by Kevin Goom. So I started small and worked up to a full port of the PICAXE code in C. The only thing I left out is the indicator LED, but that's simple enough to add later.

Jason at AtomSoft sent me a couple Nokia 7110 LCDs. Thanks Jason! They're nice cheap little 96x65 monochrome graphic LCD's if you can find them. In this project I build a breadboard connector for the display and write some PIC 18LF1330 code and some 18F2550 code to drive the display
